Cumulus clouds are low-altitude clouds characterized by their fluffy, cotton-like appearance. They are one of the most recognizable types of clouds, often associated with fair weather and a picturesque sky. The term "cumulus" comes from the Latin word meaning "heap" or "pile," which aptly describes their typical shape. These clouds usually have a flat base and appear as white or light gray tufts that can resemble cauliflower heads.

Formation of Cumulus Clouds

Cumulus clouds generally form at altitudes ranging from 200 to 2,000 meters. They are formed by a process called convection. As the sun heats the Earth's surface, warm air rises. As this air ascends, it cools, and when it reaches its dew point, water vapor condenses into tiny droplets, forming a cloud. This process is influenced by factors such as humidity and temperature gradients.

Weather Implications

Cumulus clouds are generally indicators of fair weather, especially when they are small and scattered. However, under the right conditions, they can develop into larger cumulonimbus clouds, which are capable of producing thunderstorms, heavy rain, and severe weather.
